HARROW.

SPECIFICATION forming part of Letters Patent No. 319,894, dated June 9, 1885.

Application filed February 9, 1885. (No model.)

T0 on whom it may concern.-

Be' it known that I, AUSTIN G. Evans, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Harrows; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in harrows.

My invention relates to that class of harrows which are in sectionshinged together, the outside sections being operated by a longitudinal lever extending centrally over the middle section and connected by chains with the former, said lever being free to move toward either side of the rear end in elevating the sections.

This invention is designed as an improvement upon my former patents, dated November 1, 1881, No. 248,850, and July 24., 1883, No. 281,755, on the same implement, and is intended to simplify the parts connecting the rear of the lever with the strap or bar on the rear of the middle section.

Figure 1 is a plan View of a three-section harrow with my improvement applied thereto. Fig. 2 is a rear elevation of the same with a cross-section of the lever at the point of connection with the rear end of the middle section. Fig. 3 is a side. elevation of the middle section with the lever, the chains connecting the latter with the outside sections being removed.

A is the middle section of the harrow,which is constructed in the same manner as shown in Patent N o. 236,793, issued to me January 18, 1881, in its general form being made of wooden beams connected across the ends by a bar of iron to which the outside sections,B and B,are hinged.

Over the central longitudinal line of section A is a long lever, 0, its front end being loose in a guideway on the front bar of the section. The rear end of lever 0 extends back beyond the harrow a sufficient distance to allow of its being easily manipulated by the operator who walks behind the harrow.

Immediately over bar a, on the rear of section A, is along bow-shaped bar, I), the ends of which are bolted to bar a by bolts 1) b, which extend through the latter and through the rear ends of the outer beams of the section A, thus firmly securing bar I) to the latter. Bar b extends from one side of section A to the other, so that the harrow may be operated on the most uneven ground Without having the lever pulled off from its elevated portion by either of the side chains, a, connecting it with the outside sections. The horizontal portion of bar b is sufficiently elevated for the lever(when lying thereon) to be Within easy reach of the operator,and extends in aplane parallel with that of the harrow-section A. A short piece of chain, 0, with a ring, a, on the end encircling bar b connects the lever O with the latter. WVhen lever G is thrown to one side to elevate one of the outside sections B, ring 0 slides on bar I) to the opposite side, as seen in the dotted lines, Fig. 2. When the operator releases the lever, it is again drawn back to its normal position. The free play of the lever from one side to the other of section A on bar 1) allows either one of the harrowsections to drop below the plane of the middle section, allowing the implement to better conform to the surface of rough and uneven ground than if the lever were confined to a fixed point at the rear end of the harrow, as is the case in my former patents before mentioned, in one of which the lever rests in a fork and in the other it is held by a hook at the center of the rest-bar. The lever being connected with the bar-bis at all timesin readiness to elevate the rear of the harrow.

I claim as my invention- 1. In a three-section harrow having its sections flexibly connected together, a lever with its front end loosely pivoted extending over the middle section, chains connecting said lever with the outside sections, an elevated bar on the rear of said middle section extending from side to side of the same, and a short chain connecting said lever and bar provided with a ring on its lower end encircling the latter and adapted to slide thereon, whereby said lever is free to move in ahorizontal plane over said middle section in elevating the outside sections without disconnecting it from said elevated bar, as set forth.

5 2. In a three-section harrow having its sections flexibly connected and operated by a lever pivoted over the middle section and connected by ch ains with the outside sections, the combination,with the middle section and said 10 lever, of an elevated bar on the rear end of said middle section and parallel therewith,its ends bent downwardly and attached to the latter, and a chain connecting said bar and lever together whereby said lever maybe freely I 5 operated from side to side of said middle sec- AUSTIN C.
